You're on your way to the tattoo salon to get a spine tattoo, you wanted to do it since you were 15, now in your 20s you can go do it on your own. A few weeks later you net your boyfriend, you completely forgot to tell him about the tattoo, but as you were getting intimate and you got on your hands and knees he gasped.

"What...oh...right... I forgot to tell you about that" you chuckle

He kept silence but traces with his finger your spine with the tattoo... He whimped and whisper in an hoarse voice

"Not a good idea... I'm gonna last five minutes tops if I'm looking at that..."
